摘　　要：膨胀土(岩)是一种多裂隙性、胀缩性地质体,其黏土矿物具有强亲水性,土体胀缩作用对渠道工程具有严重破坏性。因此,在对膨胀土渠坡监测过程中,除传统的渠坡变形等监测项目外,土壤含水量、吸力等是一个新的重要监测量,此外,膨胀土(岩)受含水量变化产生的反复胀缩变形以及开挖和降雨等因素引起的变形规律的研究,都是传统监测方法和手段无法完成的任务。研究提出了一种基于传感器、互联网、土木工程和计算机等技术的渠坡位移、水位、水分、水势、土温、气温、降雨量以及坡面梁结构钢筋计等多传感器的自动化综合监测系统。实现对膨胀土(岩)渠坡(或边坡)进行实时在线自动化监测、无线数传、数据的电脑和手机客户端管理与浏览以及预警等功能,为研究膨胀土(岩)渠坡变形破坏机理及处理设计有效性评价提供了基础资料和依据。Expansive soil （ rock） is a kind of multi-fractured, swell-shrinking geological body, which contains strong hy-drophilic clay minerals, and the swell-shrinking of soil has a severely destructive effect on canal project. Therefore, soil mois-ture content and soil suction are significant factors in monitoring process of expansive soil slope except for traditional monitoring objects such as slope deformation, etc. However, the research on the repeated swell-shrinking deformation due to water content variation and the deformation laws due to excavation and precipitation of expansive soil cannot be realized by traditional monitoring tools. Based on sensors, the Internet, civil engineering and computer science and technology, an automatic integrated monitoring system with multi-sensors is suggested for monitoring of slope displacement, water level, water moisture, water potential, soil temperature, air temperature, rainfall and surface beam structure（ steel bar meter） . The system has realized the functions of real-time online automatic monitoring, wireless data transmission, data management by PC and mobile client as well as browsing and pre-warning for expansive soil slope.
